Abstract
In this work, computer simulations are executed in order to detect the presence of an object which passes through the area illuminated by ultrasonic transmitter. In simulations, object which has a constant speed can be detected by only observing received signal level on ultrasonic receiver, not by using Doppler Effect or Fast Fourier Transform. Additionally, alterations on speed and distance of the object causes sensible alterations on received signal level on ultrasonic receiver. According to simulation results, a simple way for detecting speed of objects is able to be introduced by using more simple signal processing techniques compared to Doppler Effect or Fast Fourier Transform related techniques.
